Project background

Shell Prelude is the largest floating offshore facility in the world, at 488m long, 74m wide and displacing about 600,000 tonnes of water. Construction requires some 260,000 tonnes of steel, with Prelude’s turret the largest ever built. The asset will be moored at a depth of 250m for 25 years without dry docking, in the Browse Basin, offshore northwest Australia. Prelude has been designed to withstand category five cyclones and its technology has generated over 150 patents.
